payKey issue

I'm trying to setup a payment using the following codes:

response = @gateway.setup_purchase(
          :return_url => url_for(:action => :done, :params => {:order => @order.number}),
          :cancel_url => url_for(:action => :cancel, :params => {:order => @order.number}),
          :ipn_notification_url => url_for(:action => :ipn, :params => {:order => @order.number}),
          :receiver_list => recipients
      )

then, i redirect user to paypal site using the following logic

if response[:payKey].present?
        redirect_to @gateway.redirect_url_for(response[:payKey])
else
        #something else to happen
end

I've seen response[:payKey] is nil sometime. That's why it is not redirecting to Paypal. Why response[:payKey] is missing and what should I do actually do to resolve this?

FYI: I'm trying to setup a Chained payments with primary recipient.

Thanks in advance.

the response body seems to have changed?

i get it to work by calling response.pay_key

try doing a print of the response body and you should see it in there for debugging

What does response.request return?

Also have a look at response.request and response.request.message

response.request has this:

{"PayRequest"=>{"requestEnvelope"=>{"detailLevel"=>"ReturnAll", "errorLanguage"=>"en_US"}, "actionType"=>"PAY", "cancelUrl"=>"http://REMOVED.com/cancel?order=6426480503", "returnUrl"=>"http://REMOVED.com/done?order=6426480503", "ipnNotificationUrl"=>"http://REMOVED.com/ipn?order=6426480503", "currencyCode"=>"USD", "receiverList"=>{"receiver"=>[{"email"=>"seller@gmail.com", "amount"=>"1.76", "primary"=>"true"}, {"email"=>"affiliate@gmail.com", "amount"=>"0.21", "primary"=>"false"}, {"email"=>"siteowner@gmail.com", "amount"=>"0.1", "primary"=>"false"}]}, "reverseAllParallelPaymentsOnError"=>"false"}}

response.request.message:
NoMethodError Exception: undefined method `message' for #Hash:0x007f9e7e5603c8

I thought the error message was in response.request, you actually get an array of error messages from response.error

You can get the message by accessing

response.error[0].message
